The mass–luminosity (-ML), mass–radius (-MR), and mass–effective temperature (- M Teff)
diagrams for a subset of galactic nearby main-sequence stars with masses and radii …

Chemical Cartography, or map**, of our Galaxy has the potential to fully transform our
view of its structure and formation. In this work, we use chemical cartography to explore the …

The spatial distribution, Galactic model parameters, and luminosity function of cataclysmic
variables (CVs) are established using reestimated trigonometric parallaxes from Gaia DR3 …

We performed detailed photometric and astrometric analyses of the open star clusters
Berkeley 68 and Stock 20. This was based on ground-based CCD UBV photometric data …

A detailed analysis of ground-based CCD UBV photometry and space-based Gaia Data
Release 3 (DR3) data for the open clusters King 6 and NGC 1605 was performed. Using the …

This paper presents photometric, astrometric, and kinematic analyses of the open clusters
NGC 189, NGC 1758 and NGC 7762 based on CCD UBV photometric and Gaia Data …

We estimated the Galactic model parameters by means of a new approach based on the
comparison of the observed space density functions per absolute magnitude interval with a …

This study calculated astrophysical parameters, as well as kinematic and galactic orbital
parameters, of the open clusters NGC 1664 and NGC 6939. The work is based on CCD …

We present photometric, astrometric, and kinematic studies of the old open star clusters
NGC 1193 and NGC 1798. Both of the clusters are investigated by combining data sets from …

We present a new formula for absolute magnitude determination for late‐type dwarf stars as
a function of (g–r) and (r–i) for Sloan photometry. The absolute magnitudes estimated by this …
